Perhaps you should try some spelling variations:
"i cycles increases" » "i cases increased" (Expand Search), "_ cycles increases" (Expand Search), "6 cycles increases" (Expand Search), "8 cycles increases" (Expand Search)
"auc values decrease" » "auc values increased" (Expand Search), "auc largest decrease" (Expand Search)
"c large decrease" » "c marked decrease" (Expand Search), "c large increases" (Expand Search), "c large degree" (Expand Search), "_ large decrease" (Expand Search), "a large decrease" (Expand Search), "i large decrease" (Expand Search)

Try widening your search to All Fields.

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (((("auc values decrease") OR ("i cycles increases"))) OR ("c large decrease"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"auc values decrease\") OR (\"i cycles increases\"))) OR (\"c large decrease\"))".
• Removing quotes may allow a broader search: (((( auc values decrease ) OR ( i cycles increases ))) OR ( c large decrease )).
• Adding a wildcard symbol may retrieve word variants: (((("auc values decrease") OR ("i cycles increases"))) OR ("c large decrease"))*.
